The combination of the chocolate bits in the cake, the slightly crunchy graham cracker crust and the topping that is completely homemade but tastes JUST like marshmallows gave these cupcakes all the components of a true s'more.
This batter was all made using one bowl, gotta love that. People not suffering from altitude can use a mixer for their cake batter. To avoid too much air getting in, I mixed everything by hand. I'd suggest using a mixer if you're not in the mountains. One of the other things I was all too please about after these cupcakes came out of the oven was that they didn't sink in the middle... a result of altitude (among several others).
Ingredients
Chocolate Cake Batter: adapted from Hershey's
1 3/4 cup flour
3/4 cup Hershey's unsweetened cocoa powder
2 cups sugar
1 tsp baking soda
1 tsp salt
1 cup whole milk
1/2 cup canola oil
2 tsp vanilla
2 eggs
1 cup boiling water
1 bag Hershey's milk chocolate chips
Graham Cracker Crust
20 Graham crackers (crush up)
6 Tbsp melted butter
pinch of salt
2 tsp sugar
Marshmallow Frosting
4 egg whites
1 cup sugar
1 tsp vanilla
pinch of salt
Directions
Cake:
Mix all dry ingredients (flour, cocoa, sugar, baking soda and salt) in a large bowl.
Add milk, oil, vanilla and eggs straight into the bowl and thoroughly mix everything together.
Add boiling water and combine.
It will be runny.
Graham Cracker Crust:
Put 20 broken up graham crackers into a food processor and pulse until crushed.
In bowl mix crushed graham crackers, salt, sugar, and melted butter with a fork.
Marshmallow Frosting:
Add egg whites, sugar and salt to bowl over simmering water (or double broiler). Cook, stirring constantly, until sugar is dissolved and mixture is hot. About 5 minutes. Add hot mixer to a bowl or stand mixer and beat on high until stiff peaks form.
Assembly
Line cupcake tin with cupcake liners. Scoop 1 Tbsp of graham cracker mixture into each cup and press the crust gently with the back of the spoon to pack it tightly in the bottom of the cup.
Scoop in batter on top til about 2/3 the way full.
Drop chocolate chips on top of batter (be generous). Bake at 375 for 15 minutes (high altitude) or 350 for 18-22 min.
Pipe frosting onto completely cooled cupcakes. May use a ziploc bag with the corner snipped off if you don't have a piping bag! After piping my cupcakes I decided to give it a whirl and try to toast the marshmallow fluff topping with a lighter... totally worked! Took a while, but they got that yummy toasted marshmallow taste that is essential to s'mores. I totally had a picture of that, but the boyfriend got confused and took the wrong container of cupcakes to work to share with the guys before I got the pictures taken. (Sorry I didn't get any pictures of the frosting process... I was just too excited!
